Hi, I need to use ddrescue on the root partition of my laptop.
So I need to have the root partition mounted in read-only mode. How can I do that? Note that "mount -o remount,ro /" gives an error "mount point is busy" apparently because various log files are open in write mode. Using the recovery mode via GRUB (which mounts / in read-only mode) is useless because the system remounts it later as rw. Or is there a way to force a remount in read-only mode? (I could probably trigger a disk error to make the kernel remount / as read-only, but well...) -- Vincent Lefèvre <vinc...@vinc17.net> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
